5 Written questions

5 Matching questions

  1. destructive interference
  2. units of density
  3. interference
  4. interference of waves with different frequencies
  5. in phase waves
  1. a the resultant wave is smaller (of lesser amplitude) than either one of its components
  2. b a pair of waves are considered in phase when their peaks (maximum values) and troughs (minimum values) occur at the same time and in the same location
  3. c kg/cm cubed
  4. d when multiple beams arrive at an identical location at exactly the same time and thereby lose their individual characteristics and combine to form a single wave
  5. e when the frequencies of the waves differ, both constructive and destructive interference occur

5 Multiple choice questions

  1. all waves carry energy
  2. that wave is a sound wave
  3. the wave is not a sound wave
  4. sound is a mechanical longitudinal wave that moves by compression and rarefaction--particles in the medium vibrate back and forth from a fixed position
  5. there are 7 acoustic parameters: period, frequency, amplitude, power, intensity, wavelength, propagation speed----wif papp

5 True/False questions

  1. sound waves are also known assound pulses through biologic tissue or media and reflections arising from structures in the body return to the xducer and are processed into images

          

  2. how does ultrasound worksound pulses through biologic tissue or media and reflections arising from structures in the body return to the xducer and are processed into images

          

  3. what kind of line does sound travel insound is a mechanical longitudinal wave that moves by compression and rarefaction--particles in the medium vibrate back and forth from a fixed position

          

  4. what is constructive interferencethe resultant wave is smaller (of lesser amplitude) than either one of its components

          

  5. what are some different types of wavessound, light, magnetic, and heat
